We are having some issues using aiStandardSurface shader and aiToon shader connected within a aiSwitch.
The problem is that connecting the aiToon to the aiSwitch, the aiStandardSurfaces shaders becomes flat, even without selected the aiToon's index in the aiSwitch shader.
Whenever i disconnect the aiToon shader from the aiSwitch, the aiStandardSurface become as normal.
I've attached a Maya scene as example.
Thank you very much!
